iMPROVEMENT IN SPRING BED'BOTTOMS.

Specification forming part of Letters Patent No. 132,728, dated November5, 1872.

To all whom it may concern:

Be it known that I, ROYAL W. MOINTYRE, of Oregon, in the county of Daneand State of Wisconsin, have invented certain new and usefulImprovements in Spring Bed-Bottoms, which are fully set forth in thefollowing specification and accompanying drawing forming a part of thisspecification.

In the drawing like letters in the different figures represent likeparts.

Figure 1 is a top view Fig. 2 is an end view; Fig. 3, a perspective viewof the adjustablebox; and Fig. 4 is a perspective view of thespring-holder.

Nature.

I My invention consists of devices for renderin g the bed-bottomextensible and adjustable to bedsteads of difierent widths.

A represents a four-square adjustable box, provided with flanges a, andon three of the sides of the box a stop or shoulder, 11, each. stopbeing a difterent distance from the end of the box, as seen in Fig.3. Brepresents cross-bars for holding the boxes A. These bars are made aproper thickness to fit in the boxes, and wide enough to extend aboveand form supports and stops for the boxes, and are provided with slots 0c to receive the upper sides of the boxes, as shown in Fig. 2. 0'represents head and foot guards, consisting of cross-bars, supported bytwo standards, for holding'the bed-clothes from the springs to protectthe clothes from injury and from interferingwith the free operation ofthe springs. D represents metallic spring-holders, consisting of ametallic plate with two screw-holes, as shown in Fig. 4. of the drawing.E repre- -with the flanges a bearing against the ends of the bars, asshown at A in Fig.1 of the drawing then, by turning the boxes onefourtharound on one side only of the bottom, it is adjusted to a wider bed,and so on till the three sides having stops are turned up, each turnincreasing the width of the bottom; and by a corresponding change oftheboxes on the other side of the bottom three additional and greaterwidths are produced.

When the bed-bottom is in proper position on the bedstead the edges ofthe flanges a rest on the top of the side rails, and being sharp embedthemselves in the rails and thus prevent the bottom from sliding off therails.

Claim.

WVhat I claim, and desire to secure by Letters Patent, ina bed-bottom,isa The adjustable boxes A, having flanges a and graduated stops b,'incombination with bars B, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this7th day of August, 1872.

ROYAL W. MCINTYRE.
